Find LCM of 900,814,391,680,761 with Prime Factorization
2 | 900, 814, 391, 680, 761 |
2 | 450, 407, 391, 340, 761 |
5 | 225, 407, 391, 170, 761 |
17 | 45, 407, 391, 34, 761 |
45, 407, 23, 2, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 17 x 45 x 407 x 23 x 2 x 761 = 217985862600
Therefore, the lowest common multiple of 900,814,391,680,761 is 217985862600.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
900 x 814 x 391 x 680 x 761 = 148230386568000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
814 : 1, 2, 11, 22, 37, 74, 407, 814
391 : 1, 17, 23, 391
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,814,391,680,761, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
814:2x 11x 37
391:17x 23
680:2x 2x 2x 5x 17
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 17 = 680
Therefore, the value for common factors is 680.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 148230386568000/(1x680)
LCM = 148230386568000/680
LCM = 217985862600
Thus, we can understand that the LCM of 900,814,391,680,761 is 217985862600.
